hey everyone! 🌍 did you know that octopuses have three hearts? yep, TWO pump blood to the gills, while the third one pumps it to the rest of the body. that's wild, right? 🐙💓 also, their blood is blue because it contains copper-based hemocyanin instead of iron-based hemoglobin like ours. nature is amazing! hope y'all are having a great day. feel free to share your favorite fun facts below!
